Now the constructor of AbstractDiskWriter takes filename as an
argument and filename argument is removed from openFile(),
initAndOpenFile(), openExistingFile() interface. storeDir
member and its accessor functions are removed from DiskAdaptor
because it is not used anymore. size() member function of
DefaultDiskWriter, DirectDiskAdaptor and MultiDiskAdaptor now
can be called without opening file.

BitfieldMan::getMissingIndexes family functions now takes
unsigned char* bitfield instead of stl container for efficiency.
PieceSelector::select now takes this
bitfield. RarestPieceSelector::select now also performs
efficiently for this change. bitfield namespace is introduced
and it has several helper functions to handle basic bitfield
operations such as test, count set bits, etc.

Added 'falloc' parameter for --file-allocation option. 'falloc'
allocation mode uses posix_fallocate() system call to allocate
file on disk. If you are using newer file systems such as ext4
(with extents support), btrfs or xfs, 'falloc' is your best
choice. It allocates large(few GiB) files almost instantly.
Don't use 'falloc' with legacy file systems such as ext3 because
it takes almost same time as 'prealloc' and it blocks aria2
entirely until allocation finishes. 'falloc' may not be
available if your system doesn't have posix_fallocate() system
call.

Use LongestSequencePieceSelector for HTTP/FTP/BitTorrent
integrated downloads. This PieceSelector subclass finds the
longest continuous sequence in the available missing pieces and
selects the last index of such sequence. This makes HTTP/FTP
connections less interrupted by the pieces obtained by
BitTorrent peers.

Calculate piece hash when data is arrived if the data is arrived
in
order. This removes additional read operation for hash
calculation.
If the data is arrived in out of order, the hash is calucated
when the
piece is completed. This is the same behavior as the old
implementation.

catched exception.

Rewritten SharedHandle. Now copy constructor taking raw pointer
has
keyword explicit and SharedHandle's default constructor
initializes
its internal obj to null, old implementation initializes it
using
obj's default constructor.
To assign null, write SharedHandle<T> x(...); x.reset();

Preallocate non-requested file which is adjacent forward to

file('requested' files means the files given in --select-file

Lower CPU load when --max-download-limit is used.
There is up and down in speed indicator when enabling
http-pipelining but a download goes well. I think the problem is
that
because http-pipelining is enabled, DownloadCommand is created
for
each segment and in its constructor, PeerStat::downloadStart()
is
called. In PeerStat::downloadStart(), speed calculation object
is
reseted, which makes download speed zero.
* src/DownloadCommand.cc
Rewritten using accumulate.
* src/RequestGroupMan.cc (calculateStat)
Code clearnup.
* src/FtpNegotiationCommand.cc
* src/HttpResponseCommand.cc
* src/Piece.{h, cc}: Added SubPiece infrastructure to track down

I've rewritten lots of files and now some headers have forward
class declarations to reduce compile time.
The implementation is extremely alpha stage, I recommend to use this
for testing purpose only.
